Did you know that the most overlooked discount is a customer-service survey, says Kendal Perez, creator of the website Hasslefreesavings.com? Stores like Dick’s Sporting Goods and JCPenney (my favorite store) print a phone number or link on receipts to get feedback on your experience. In return, you get a coupon! Banana Republic and the Gap each offer a 20 percent discount on your next purchase. 
Want more coupons? Clike “Like” for certain stores on Facebook: Quiznos and Blimpie’s offer a free sub and The Limited gives you a $15 coupon. So started clicking, liking and saving 🙂
